2006-02-07[PATCH] remove bogus asm/bug.h includes.Al Viro
A bunch of asm/bug.h includes are both not needed (since it will get pulled anyway) and bogus (since they are done too early). Removed. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2005-11-29[MTD] CFI: Use 16-bit access to autoselect/read device id dataTodd Poynor
Recent models of Intel/Sharp and Spansion CFI flash now have significant bits in the upper byte of device ID codes, read via what Spansion calls "autoselect" and Intel calls "read device identifier". Currently these values are truncated to the low 8 bits in the mtd data structures, as all CFI read query info has previously been read one byte at a time. Add a new method for reading 16-bit info, currently just manufacturer and device codes; datasheets hint at future uses for upper bytes in other fields.

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This updates the Primary Vendor-Specific Extended Query parsing to version 1.4 in order to get the information about the Configurable Programming Mode regions implemented in the Sibley flash, as well as selecting the appropriate write command code. This flash does not behave like traditional NOR flash when writing data. While mtdblock should just work, further changes are needed for JFFS2 use.

2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-06-29[MTD] NAND: Reorganize chip lockingThomas Gleixner
The code was wrong in several aspects. The locking order was inconsistent, the device aquire code did not reset a variable after a wakeup and the wakeup handling was not working for applications where multiple chips are sharing a single hardware controller. When a hardware controller is available the locking is now reduced to the hardware controller lock and the waitqueue is moved to the hardware controller structure in order to avoid a wake_up_all(). The problem was pointed out by Ben Dooks, who also found the missing variable reset as main cause for his deadlock problem. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-01-05[MTD] Bug in 2.6.10 mtd driver for physmem mapped flash chipsDavid Woodhouse
The patch below fixes a small but fatal bug in the code that handles non-buswidth-aligned writes. The problem is that the code used the same index in both map_word and buf, therefore putting the wrong words in the map_word that partially contains old data and partially contains new data. The result: corrupt data is being written. Signed-off-by: Koen Martens <kmartens@sonologic.nl> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2004-11-16MTD: Provide XIP support for Intel flash chips.David Woodhouse
This allows for MTD support to be used on flash memory which is also used for XIP purposes, either XIP kernel or XIP userspace. The whole idea is to relocate functions actually modifying the flash state away from array mode to ram and run them with interrupt disabled. When the flash needs some time to complete a certain operation, we poll the processor for pending (but still masked) interrupts, and when they occur we suspend the flash operation in order to unmask interrupts and let the system run again.

2004-10-21MTD: NOR flash chip driver updatesDavid Woodhouse
Mostly from Eric Biederman for supporting BIOS flash. - Move support firmware hub style lock and unlock into fhw_lock.h (from cfi_cmdset_0002) - Move cfi_varsize_frob into cfi_util from cfi_cmdset_0001.c and cfi_cmdset_0002.c - reduce gen_probe probe failuers to a debug level message - Modify cfi_fixup to take a struct mtd_info instead of a struct map_info So that the fixup routines can modify the mtd functions. - Modify cfi_cmdset_0001() to allocate and initialize the mtd structure before calling cfi_fixup. - Modify cfi_cmdset_0002() to allocate and initialize the mtd structure before calling cfi_fixup. - Refactor the hard coded fixups in cfi_cmdset_0001 and cfi_cmdset_0002 so the improved cfi_fixup infrastructure. - Rewrote amd76xrom and ichxrom. They now report their starting physical address in their name. They now both handle multiple bankwidth configurations They both can create multipe mtd devices. They both now assume the rom windows are properly opened by the BIOS or whatever runs previous to them. Their code is now synchromized so it is almost identical, and could be a starting point for a x86_rom_probe. Signed-Off-By: David Woodhouse <dwmw2@infradead.org>
